Abstract (en)
[origin: WO2012004675A2] In a process for producing polyethylene having a molecular weight of at least 1 x 106 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition comprising a particulate support having an average particle size, d50, of less than 58 microns and a Group 4 metal complex of a phenolate ether ligand carried by the support.
